Electricity - Coggle Diagram
Electricity
Materials can become elctrically charged
Electric charge is a property of matter
Electric charge is a property that allows an object to exert an electric force on another object without touching it
The space around a particle through which an electric charge can exert this force is an electric field
Static charges are the caused by the movement of electrons
A static charge is a buildup of electric charge in an object caused by the presence of many particles with the same charge
Charging by Contact
When two uncharged objects made of certain materials touch each other, electrons move from one material to the other
How materials Affect Static Charging
Charging by contact occurs when one material's electrons are attracted to another material more than they are attracted to their own
Charging by Induction
The buildup of a charge without direct contact is Induction
Charge Polarization
Induction can build up a charge by changing the position of electrons
Charges can move from one place to another
Static charges have potential energy
Electric Potential Energy
Electric potential energy is the energy a charged particle has due to its position in an electric field
Charge Movement
When certain things move from a higher to lower position, some of its potential energy is used to move it. Along the way, some of its potential energy can be sued to do other work
Lightning
Lightning is a high-energy static discharge
Materials affect charge movement
Superconductors
Superconductors are materials with practically no resistance at extremely low temperatures
